Baby-boomer Aucklanders are snapping up coastal property around the North Island, leaving slim pickings for those looking for a traditional beachside bach.

Real estate agents in top holiday spots say "boomers" looking to secure their retirement are even starting to rival overseas investors in their passion for buying desirable land.

In the ever-popular Coromandel, demand for prime coastal land was "exceptionally good", said Richardson real estate agent Kim Radick.

Coastal sections range from $475,000 to $650,000. Even the most basic coastal home can go for almost $1 million.

The traditional Kiwi bach and sleep-out at Otautu Bay pictured above is in a prime beachfront position. The 824sq m section is ripe for redevelopment, with panoramic sea and island views. And it could be yours for the bargain price of $960,000.
